Background and Objective: Leukemia is one of the top five cancers in Iran. Aside from physical issues, the disease causes a variety of social and psychological issues for patients. In this regard, one aspect that cancer may affect is quality of life, which can lead to anxiety. The collaborative care model is a novel nursing model that improves treatment outcomes through collaboration. As a result, the purpose of this study is to look into the impact of a collaborative care model on quality of life and anxiety in leukemia patients. Methods:The current non-randomized clinical trial, which included a control group, was conducted on 60 leukemia patients at Firoozgar and Rasoul Akram hospitals in Tehran (affiliated to Iran University of Medical Sciences). The hospitals were randomly divided into two groups: control and intervention, and patients were chosen at random from each hospital using a convenience sampling method. The collaborative care model was implemented in the intervention group, while no specific measures were taken in the control group. Patients in both groups' quality of life was measured using the Quality-of-Life Questionnaire in Oncology Patients before, one, and two months after the intervention, and their anxiety was measured using the Beck Anxiety Inventory. Both groups completed their questionnaires using a self-report method.Results: In terms of demographic characteristics, there was no statistically significant difference between the two groups (p>0.05). Prior to the intervention, no statistically significant difference in mean anxiety, quality of life, and its dimensions was observed between the two groups (p>0.05). Following the intervention, a statistically significant difference in mean anxiety and quality of life scores was observed between the two groups (p<0.05), indicating a decrease in anxiety and an increase in quality of life among patients in the intervention group. Conclusion:Based on the findings, it appears that the collaborative care model has a positive effect on reducing anxiety and improving quality of life in leukemia patients, and it is preferable to use this model when caring for this group of patients.

Background: Embryo quality may affect birth weight among neonates born through assisted reproductive technology. There are very limited studies assessing the adverse effect of transferring a poor-quality embryo with a good-quality one on neonatal outcomes. Objective: The aim of this study was to evaluate the effect of double embryo transfer (DET) with one good-quality embryo (GQE) plus a poor-quality one on the birth weight of newborns conceived by in vitro fertilization in both fresh and frozen-thawed embryo transfer cycles. Materials and Methods: This study was conducted at Yazd Reproductive Sciences Institute, Yazd, Iran. A total of 626 women were classified into three groups according to the embryo quality: single embryo transfer with a GQE (group A); DET using two GQEs (group B); and DET using one good-quality and one poor-quality embryo (group C). The primary outcome was singleton birth weight which was compared between the three groups among fresh and frozen-embryo transfer cycles. A comparative analysis was also performed regarding the effect of vitrification procedures on neonatal birth weight within each of the three embryo quality-based groups. Results: The mean birth weight and the rate of preterm birth were similar between the three groups (p = 0.45 and 0.32, respectively). There were also no significant differences found in the vitrification comparative analysis between and within the groups with regard to birth weight. Conclusion: Our results showed that a poor-quality embryo did not have a significant influence on a good-quality one regarding neonatal birth weight when transferred together. Key words: Embryo quality, Birth weight, Frozen-embryo transfer, Fresh embryo transfer, Single embryo transfer, Double embryo transfer.

Background: Medical students must have sufficient expertise to provide health services to the old as the global population of the elderly grows. Few research, however, have looked into this issue among medical, health, and nursing students. As a result, the purpose of this study was to look into the knowledge of medical, health, and nursing students on aging and related variables. Methods:In the year 2020, a cross-sectional study was done in Yazd, Iran. The research community was founded by Yazd University of Medical Sciences students. A total of 105 students from medical, health, and nursing were needed for the study. Two tools were used to collect data. a) A list of demographic characteristics Age, gender, level of education, and b) The Facts on Aging Quiz are among the items on this checklist (FAQI). FAQI is made up of 25 things in four dimensions, each of which can be answered with one of three options: "correct," "don't know," or "false." A higher score suggests a better position and a greater understanding of aging facts. Results:Students were 29 years old on average. Women made up almost 75% of those who took part. Only over a quarter of the attendees went to conferences and seminars on senior health. The majority of students in all three areas (medicine, health, and nursing) had never volunteered with the elderly before. Medical, nursing, and health students scored 11.093.4, 8.83.1, and 11.82.8 out of a possible 25 points on their understanding of aging facts, respectively. Only the area of study was statistically associated to the mean score of facts of aging among the demographic variables, indicating that the knowledge score of medicine and nursing students was lower than that of health students. Conclusion:The students that took part in this study lacked appropriate awareness of the facts of aging. Students' understanding in this area must be increased through the implementation of relevant educational programs.
